Open Source tools play a pivotal role in the realm of Vulnerability Assessment and Penetration Testing (VAPT). These tools are indispensable for identifying vulnerabilities, assessing network security, and ensuring the robustness of systems against cyber threats.

The open-source nature of these tools means that they are developed and improved through collaborative efforts from a global community of security experts, which leads to rapid updates, a wide range of features, and generally high levels of reliability and security. This collaborative approach also ensures that these tools are often at the forefront of identifying and mitigating the latest vulnerabilities and attack vectors.

Three recent open-source tools in the VAPT market include:

1. GVM (Greenbone Vulnerability Management): An advanced framework that provides a full-featured scan engine for vulnerability scanning and management. It's the successor to OpenVAS and stands out for its comprehensive and up-to-date vulnerability scanning capabilities.

2. Faraday: A collaborative penetration testing tool that integrates various other open-source tools for a more cohesive testing process. It offers real-time data sharing among testers and supports a wide range of plugins.

3. ArcherySec: This tool is designed to be a central place for managing and executing security scans, combining tools for web application scanning, network scanning, and static code analysis. It's particularly useful for integrating various security tools into a single dashboard for ease of management.

The importance of open-source VAPT tools lies in their accessibility and adaptability. Being free, they allow even small and medium-sized enterprises to access sophisticated testing tools, democratizing cybersecurity. Additionally, since the source code is available, these tools can be customized to fit the specific needs of an organization, which is a significant advantage over proprietary solutions.

Below is a list of ten such tools, along with details about their inception, purposes, examples of use, and their respective advantages and disadvantages:

1. Wireshark

- Developed By: Originally by Gerald Combs in 1998.

- Purpose: Network protocol analyzer used for network troubleshooting, analysis, and protocol development.

- Examples: Debugging network issues, and monitoring network traffic for malicious activity.

- Advantages: Deep inspection of hundreds of protocols, live capture, and offline analysis.

- Disadvantages: Steep learning curve; raw data can be overwhelming to analyze.

2. Metasploit Framework

- Developed By: Originally by H.D. Moore in 2003.

- Purpose: Used for developing and executing exploit code against a remote target machine.

- Examples: Testing network defenses by simulating attacks on known vulnerabilities, and conducting advanced penetration tests.

- Advantages: Large database of exploits, regularly updated, highly customizable.

- Disadvantages: Complexity for beginners, can be resource-intensive.

3. Nmap (Network Mapper)

- Developed By: Gordon Lyon (Fyodor) in 1997.

- Purpose: Network discovery and security auditing tool.

- Examples: Scanning network ports to find open ports and identifying services running on a host.

- Advantages: Flexible, supports a wide range of scanning techniques.

- Disadvantages: Scans can be slow; some learning is required to use them effectively.

4. OWASP ZAP (Zed Attack Proxy)

- Developed By: OWASP (Open Web Application Security Project) in 2010.

- Purpose: Web application security scanner.

- Examples: Identifying vulnerabilities in web applications, such as SQL injection, and cross-site scripting.

- Advantages: User-friendly for beginners, active community support.

- Disadvantages: Performance can be an issue with large applications.

5. SQLMap

- Developed By: Bernardo Damele Assumpcao Guimaraes in 2006.

- Purpose: Automates the process of detecting and exploiting SQL injection flaws.

- Examples: Testing database security level, automating SQL injection discovery.

- Advantages: Supports a wide range of database servers and, powerful detection engine.

- Disadvantages: Can be overly aggressive, potentially leading to issues on the target system.

6. Nessus

- Developed By: Renaud Deraison in 1998.

- Purpose: Vulnerability scanner which scans for known vulnerabilities, configuration issues, and potentially risky software.

- Examples: Regular vulnerability scanning of corporate networks, and compliance checks.

- Advantages: Comprehensive vulnerability scanning, user-friendly interface.

- Disadvantages: The free version has limited functionality compared to the professional version.

7. John the Ripper

- Developed By: Openwall Project in 1996.

- Purpose: Password cracking tool.

- Examples: Testing password strength within an organization, recovering lost passwords.

- Advantages: Supports many hashing algorithms, extensible with plugins.

- Disadvantages: Requires some understanding of command-line tools, can be slow for complex passwords.

8. Aircrack-ng

- Developed By: Thomas d'Otreppe in 2006.

- Purpose: Suite of tools for assessing Wi-Fi network security.

- Examples: Monitoring Wi-Fi networks for vulnerabilities, and testing network driver capabilities.

- Advantages: Comprehensive tool for Wi-Fi security analysis.

- Disadvantages: Requires compatible wireless network adapters, illegal in some jurisdictions without permission.

9. Burp Suite

- Developed By: PortSwigger Web Security.

- Purpose: Integrated platform for performing security testing of web applications.

- Examples: Performing and automating application attacks, such as CSRF, and XSS.

- Advantages: Comprehensive set of tools, highly customizable.

- Disadvantages: The free edition has limited features, professional edition is paid.

10. Kali Linux
